Specification of Letters Patent.

Application filed March 8, 1904. Serial No. 197,117.

To all whom it may concern.-

Be it known that we, THEODORE HAROLD J OSEPH and JAMES J ACOB EHRENREICH, citizone of the United States of America, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements .in Electric-Lamp'Shade Holders, of which the following is a specification.

Our invention relates more especially to a shade-holder designed for use with incandescent-lamp sockets.

Our object is to construct a shade-holder which will hide the rough edge of the shade and at the same time be e'flective in operation, easy of manipulation, and cheap to manufacture.

With these ends in view our device is made of a single piece, has a single clamping means, securely grips both the shade and the socket, and has a portion completely surrounding and covering the raw edge of the shade.

Essentially our device consists of a split ring provided with an internal groove to cover and grasp the lips of a shade, a flat band with free ends to grip the shell of a socket, radial arms integral with and connecting the band and the ring, and means for detachably clamping the ends of the band to gether, whereby the band is made to grip the socket, and at the same time the split ring is made to close about and grasp the lip of the shade.

The device will be described in detail by reference to the accompanying drawings.

Figure 1 is an elevation of our improved holder in attached position on a socket and shade, certain portions being broken away to better show the construction. Fig. 2 is a plan view of a shade-holder in applied position on a shade and socket, the socket being sectioned on the line A A of. Fig. 1. Fig. 3 is a plan view of a sheet-metal blank from which our improved shade-holder is formed. Fig. iis an enlargedperspective view of the clamping means illustrated in Figs. 1 and 2. Fig. 5 is view similar to Fig. 4,but showing a modified form of clamp, a bent wire being employed for the latch. Fig. 6 is a sectional view on the line B B of Fig. 2 looking upward, the socket and shade being omitted andportions of the shade-holderbeing broken away. Fig. 7 is a section on the line C O of Fig. 6.

The lamp-socket 1, as is usual, has the shoulder 2 and the annular projection 3, be-

tween which is the recesses i, and the shade V 5 has the usual outwardly-projecting lip 6.

The shade-holder has the fiat band 7, having outwardly-turned ends 8 and 9.

10 is an outwardlyconveX and inwardlyconcave divided ring whose ends overlap and fit into each other. The band 7 and the ring 10 are joined to each other by the arms 11, which are integral therewith and, as shown, are slightly curved in a transverse direction for the sake of greater stiffness and strength. The latch 12 is formed integral with the end 8 of the band 7 and when the holder is in use engages the end 9 the band 7 then gripping the socket 1 between the shoulder 2 and the annular ridge 3 and the ring 10 grasping the periphery of the lip 7. It is to be noted that the division in the ring 10 and in the band 7 occurs between the same two of the arms 11, by reason of which when the band 7 is contracted to grip the socket 1 the ring 10 is also contracted and caused to firmly grasp the lip 6 of the shade 5. As the' latch 12 engages only the upper edge of the end 9, the ends 8 and 9 are left free to be grasped by the fingers in manipulating the holder.

Our shade-holder complete is composed of a single piece of material, being formed from a sheet-metal blank, such as is shown in Fig. 3. The strip 13 becomes the ring 10, the strip 14 becomes the band 7, the bars 15 become the arms 11, and the projection 16 forms the latch 12.

In the modified form of clamp shown in Fig. 5 thelatch 1 1 is composed of apiece ofwire bent to a U shape, one leg of the U being retained and pivoted in the turned-over end 18 of the band 7 and the other detachably engaging the outwardly-turned end 19 of the said band and extending only part way across the end 19, so as to leave room for a finger-hold on the said end. This form of latch is fastened by pressing the ends 18 and 19 together and then swinging the latch 17 around like a gate till it engages the end 19 and is unfastened by a reverse operation.

In the operation of attaching the holder the ring 10 is sprung over the lip 6 of the shade 5. Then the band 7 is slipped over the socket 1 above the ridge 3, the free ends 8 and 9 being pressed together by the fingers till the latch 12 engages the end 9. When the ends 8 and 9 are brought together, the band 7 grips the socket 1 and the ring 10 is contracted around the lip 6 and retained in that position with sufficient force to firmly hold the shade 5 and prevent it from becom ing detached.

To remove the holder and shade from the socket, the latch 12 is unhooked and the holder slipped from the socket. Then if it is desired to remove the holder from the shade the ring 10 is sprung from over the lip 6.

We claim as our invention" 1. A lamp-shade holder consisting of an internally and continuously concave split ring, to cover and grasp the lip of a shade, a flat band with free ends, to grip the shell of a socket, radial arms connecting the said band and ring, and means for detachably fastening the ends of the said band together.

2. A lamp-shade holder consisting of a flat band with free ends, a split ring provided with an internal groove and having overlapping ends, connecting-arms integral with the said band and ring, the ends of the said band and of the said ring being located between the same two arms, and means for detachably clamping the ends of the said band to gether.

3. The combination with a socket, and lamp-shade having a lip, of a shade-holder having a flat open band for gripping said socket, a split ring provided with an internal groove and having overlapping ends, for covering and grasping the periphery of said lip, radial arms integral with the said band and ring, and means for detachably clamping the ends of the said band together.

4. The combination with a lamp-shade which has an outwardly-projecting lip, and a cylindrical lamp-socket, of a shade-holder having a flat open band for gripping the said socket, an internally-concaved split ring having telescoping ends, for covering and grasping the periphery of said lip, radial arms con necting the said band and ring, the ends of the said band and of the said ring being located between the same two arms, and means for detachably clamping the ends of the said band together.

5. The combination with a lamp-shade which has an outwardly-projecting lip, and a cylindrical lamp-socket, of a shade-holder having a flat open band for gripping the said socket, an internally-concaved split ring hav ing telescoping ends, for covering and grasping the periphery of said lip, radial arms connecting the said band and ring, the ends of the said band and of the said ring being located between the same tWo arms, and means for detachably clamping the ends of the said band together, all parts of said shade-holder being integral.

6. The combination with a lamp-shade which has a lip, and a lamp-socket, of ashadeholder having a flat band with free ends, for gripping the said socket, an internally-concaved split ring having telescoping ends, for covering and grasping the periphery of said lip, arms integral with and connecting the said band and ring, the ends of the said band and ring being located between the same two arms, and a latch integral with one of the free ends and bent detachably over the other free end of said band.

7. The combination with a lamp-shade which has an outwardly projecting lip, and a lamp-socket having annular projections spaced apart to form a cylindrical recess thereon, of a shade-holder having a flat band with free ends, for gripping the said socket between the said projections, an internallyeoncaved split ring having telescoping ends, for covering and grasping the periphery of said lip, radial arms integral with and connecting the said band and ring, the ends of the said band and ring being located between the same two arms, and means for detachably clamping the ends of the said band together, whereby the band is caused to grip the socket and the ring is closed about the lip of the shade.

8. A lamp-shade holder consisting of two open rings of spring sheet metal, arms con necting the rings together, one ring having its ends bent outward radially, and the outer portion of one of said ends being furthermore bent and sprung over the other end.

9. The combination of a lampshade, a lip thereon, a ring extending over the top, side and under side of said lip, and having ends which overlap each other and which are adapted to spring toward each other for gripping and supporting the shade, a lamp-socket having a groove, a band with free ends, extending around the socket in the groove, the said ends extending outward radially from said. socket, and one of said ends extending above and over the other end, for causing said band to grip said socket, and arms connecting said ring and said band together.
